How to adjust this delay timer?

[geojay]

This delay timer is used to control the lights in a communal hall, it’s triggered by various momentary contact rocker switches located along the hall. Can anyone help with the following questions?
• How can I increase the delay? Is the component marked 1M a variable potentiometer?
• Can anyone ID the timer so I might find instructions?
• Can anyone recommend a replacement timer that would fit in the same housing?

Thanks in anticipation!

Is the component marked 1M a variable potentiometer?

Yes, and it's likely that it changes the time delay.

Can anyone recommend a replacement timer that would fit in the same housing?

No, but as that appears to be in a service cupboard, the more usual type of timer like this: https://www.cef.co.uk/catalogue/products/1291832-staircase-delay-timer and a suitable enclosure would be the obvious choice.

This MIGHT be the setting for the DIP switch if as I suspect this is an early version of the Elkay 320A timer unit. The 1Meg variable resistor provides fine tuning of the timed period.

I was just about to write the same.

How can I increase the delay?

Is the current delay around 2 minutes?

Is the current delay around 2 minutes?

The DIP switches in the picture are all in the ON postion which would be 120 mins

The modern version apears to be

320A-1 Remote Timer • Push Button Timers • Elkay Timers and Switches UK

Remote Timer 320A-1. This remote timer is ideal for use with an Elkay activator switch and other retractive or momentary activated switches.

Yes, but these are newer instructions. As the OP wishes to extend the time period, I'm guessing it's not already set to 2 hours and in between models, the DIP switches have reversed.

It is!

I think you’ve cracked it, thanks so much for your help! All four DIP switches are on so these instructions look very promising.

According to https://elkay.co.uk/wp-content/uplo...320A-1_-2235A-1_760A-2_A5_INSTRUCTIONS_AW.pdf all on equates to 2 minutes which feels about right for how it works currently.

All off is 2 minutes,all on is 2 hours according to what you posred above

My mistake, I missed the text and interpreted it the opposite way around! I’ll have a play when I’m next there and see what I find…

Thanks!

If you are trying to establish switch settings I'll suggest turning the time right down to near minimum (5-10%) when playing as 2 minutes is a hellishly long time to wait.

While 2 hours is perfect, as long as you’re being paid by the hour, didn’t drive to the job, and there is a pub around the corner!
