8. Required Daily Testing
8.1. Required Daily Testing Before Use
This Control system requires daily inspections before use, to confirm full functionality of all safety
features. Failure to do so could put an operator or bystander’s life at risk. Be aware that all safety features
must function as described below. If one system is not operating correctly it could have deadly consequences.
Make sure that the reset key is controlled by ONLY the authorized person on sight. The key allows the T4P-
GF-1U panel to be started, and reset in the case of an earth/ground fault failure. Allowing the key to remain
with the panel while being operated allows anyone to turn on and reset the box without authorization. Take the
key out once the unit is started.
This procedure will require the test plug to complete. The test plug is designed so when installed in the
locations listed below if the switches are both in the center position all receptacles will show a green indicator
because of the 300 ohm resisters used to simulate the pump and platens. If any switch is pushed down the plug
will have its resistance decreased and will generate the platen indicator to indicate a red. This will check each
platen receptacle if done one at a time. If either switch is pushed up it will decrease the resistance to the pump
receptacle and generate a red indication on the pump indicator. Any plug removed will generate a lost pilot and
give a yellow indication.
1. Check the serial plate to confirm the voltage, amperage and phase are correct for the power being
used.
2. Confirm that the platens being used match the power being used.
3. Confirm that the platens are GF compatible by inspecting the serial plate on the platen, (the model
should end in GF).
4. Inspect all cables for damage, wear or unsafe conditions. If you are not familiar with what is
safe for cords and cables get someone who is. Think safety first. If any of the cables are not safe
to use contact your maintenance department and/or Shaw Almex for repair or replacement
instructions.
5. Check the cable plugs and receptacles for signs of wear or conditions that would make them
unsafe to use. If you are not familiar with what is safe for cords and cables get someone who is.
Think safety first. If any of the cables are not safe to use contact your maintenance department
and/or Shaw Almex for repair or replacement instructions.
6. Connect the main power supply cord to the appropriate receptacle and the T4P-GF-1U box.
7. Make sure the E-Stop is reset before continuing.
8. When power is ON the Test Button Fault Indicator and three phase indication lights, L1, L2, and
L3 should be illuminated. There should be no other lights or temperature controllers on at this
time.
If this doesn’t occur remove the key and lockout and tag out the unit. Services will be
required.
9. Plug the test plugs into the platen and the pump receptacle, (these must be purchased with every
order of T4P-GF-1U boxes). Make sure the switches are in the center position.
10. Turn the reset key and the temperature controllers should turn on and indicate about 80 F or 27 C
11. At this point the green light should indicate a proper earth/ground connection.
If this doesn’t
occur remove the key and lockout and tag out the unit. Services will be required.
12. Reset the main breaker and turn each platen switch to 1M and then O . You should hear the
contactors in the box engage and disengage. If this doesn’t occur remove the key and lockout
and tag out the unit.
Services will be required.
13. Place the test cord plug into the pump and platen receptacles. When each toggle switch is used in
the down position it will generate a red light. If either switch is pushed up it will generate a red
pump indicator. If the plugs are removed this will generate a yellow indication.
If this doesn’t
occur remove the key and lockout and tag out the unit. Services will be required.
14. Place the test cord plug into the platen receptacles. When the toggle switch is used in the center it
generates a red. When the switch is put in one position it generates a green light on the platen
